The Freedom Fill Auxiliary System is a complete installation kit for your new ATTA aluminum auxiliary diesel tank. This fuel system is designed for full size Ford, Dodge, and GM/Chevrolet diesel trucks.

 

The Freedom Fill Auxiliary System meets or exceeds all DOT, EPA, and VESC-22 regulations.

 

How it works:

 

ATTA’s  Freedom Fill Auxiliary System is a computer controlled fuel system. The small computer module mounted under the dash, sense the level of the factory tank and the auxiliary tank. When the factory tank reaches approximately a half a tank, the computer box will turn on the auxiliary in-line fuel pump. This will then begin to transfer fuel from the auxiliary tank to the factory tank. When the factory tank reaches approximately three-quarters of a tank, the auxiliary in-line fuel pump will shut off. Whenever the auxiliary tank is transferring fuel, a small light on the switch will turn on indicating fuel is being transferred from the auxiliary tank to the factory tank. When the auxiliary tank is near empty, the in-line fuel pump will not turn on. The aluminum auxiliary tank will have its own 2” gauge so you know how much fuel is remaining in the auxiliary tank. If the factory fuel tank drops below a half a tank, then you know the auxiliary tank is empty. The Freedom Fill Auxiliary System has an on/off switch which allows you to deactivate power to the system.

 

The Freedom Fill Auxiliary System is designed to work with Ford, Dodge, or GM/Chevrolet full size diesel trucks. This is one of the easiest systems on the market to install to you truck. Anyone with basic mechanical skills can install this system themselves in a matter of 5 to 6 hours or better. ATTA, inc. does have an extensive installing dealer network, please contact us for a dealer near you.

The Freedom Fill Computer Box will be programed to match your specfic truck. During checkout, you will be asked to identify your make and model.

FREEDOM FILL AUXILIARY SYSTEM Instructions 

   

1. Mount the Gauge & Switch Console on desired location on dash. Note: Attach locking suction cup to console arm to mount on windshield. Clean surface area to insure proper seal of suction cup. Run wires to the underside of the instrument cluster. Insure the wires will not interfere with any moving parts (IE: brake pedals, parking brake, etc.). It may be necessary to drill a hole for routing of wires.  (NOTE: When routing wires, it is not necessary to pull wires tight, give yourself some slack).

2. Place the Freedom Fill Controller Box under the instrument panel, (It may be necessary to remove the dash panel). This can be done by using two zip-ties to attach the controller to a factory harness or bracket. Insert the Controller harness to the Controller Box. (NOTE: Color of box may differ from picture).

3. Connect the GREEN wire from the Gauge & Switch Console and Controller Harness to chassis ground. This can be done by attaching a small eyelet to the wire and using a self-tapping screw to a chassis ground. 

4. See owner’s manual for location of either a spare fuse or upfitter fuse.  Connect the RED wire off the switch to a 12 volt ignition power source.  Note: Spare & Upfitter fuses are not used in any factory system and should be used when adding any accessory part. To add the 15 amp inline fuse to the red wire, cut the red wire and place one end of the wire inside the fuse holder and clamp that side down. Place the other side of the wire to the other side of the fuse holder and clamp down. Insure each side of the fuse holder is properly in the locked position. Insert the 15 amp fuse to the fuse holder at the end of the installation.

5. Connect the BROWN wire from the Gauge & Switch Console to the BROWN wire on the controller harness. Connect the PURPLE wire from the Gauge & Switch Console to the PURPLE on the Controller Harness. Connect the short YELLOW wire from the Gauge & Switch Console to the YELLOW wire on the Controller Harness. 

6. Connect the ORANGE wire from the Gauge & Switch Console to the Factory dimmer switch wire.  This wire is used for the auxiliary gauge light. The wire can be found behind the factory dimmer switch.  It may be necessary to use a test light to determine the proper wire. (See owners manual)(Use the supplied splice to tie the orange wire to the factory dimmer switch wire).

7. Route the remaining wires (White, Black, Blue, and the long Yellow) through the fire wall and route the wires along the frame rail. Insure the wires do not come in contact with any moving parts. Use a small grommet or use a rubber boot when routing wires through firewall to insure wires will not chaff and create a short.

8. Apply the gasket sealer to both sides of the gasket of the Sending unit. Install the Sending Unit Assembly to the tank using self-tapping screws. DO NOT BEND FLOAT ARM WHEN INSTALLING SENDING UNIT INTO THE TANK. Attach the Sending unit harness to the tank. The Yellow wire attaches to the center post of the Sending unit. The Green wire attaches under any of the self-tapping screws.

9. Connect the 3/8” hose to the 3/8” supply port on the Sending Unit using a hose clamp. Connect the long 5/16” hose to the 5/16” return port using a hose clamp. Connect the short 5/16” hose to the 5/16” vent port using a hose clamp. Tighten all hose clamps to insure proper seal.

10. Remove the Lock-Bar from the auxiliary tank and throw away shipping screws. Drill a 3/8” hole approximately 2” from each end of the Lock-Bar and place a bolt in each hole. Position and center the auxiliary tank in the truck bed. Insure the auxiliary tank is placed on some sort of isolation mat. (Drop-In or Spray-In bed liners will work. Mud Flaps or a rubber mat will work also).  The front hold-down tabs of the tanks will slide under the lock-bar. Drill the rear hold-down(s) of the tank and place a bolt in the hole. Route the wires and hoses under the truck. Insure the hoses are properly tied and no sharp bend was created. Place one flat washer, one lock washer and one nut on each bolt. Tighten all bolts.

11. (A) On some GM trucks ’01-’04 it may be necessary to use the push-in adapters on the factory fill neck in place of the vent-line adapter. Disconnect the factory fill from the body of the truck. Pull the assembly down the underside of the truck to make it easier to work on and prevent metal shaving to fall into factory tank. Using a 19/32” drill bit (a 9/16” bit may used, only if the 19/32” cannot be found), drill two (2) holes into the metal portion of the factory fill neck. *Note: Insure that the holes will be on the side of the factory fill neck facing the engine side of the truck when it is bolted back to the factory position. Remove any shaving that may have been produced. Place a bead of Hyolmar around the ring of the rubber boot of the adaptor, (do not install the elbow at this time). Insert the rubber boot into the 19/32” hole of the factory fill neck. Insert the metal elbow into the rubber boot. Insure that it has a snug fit. Place one long cable-tie around each of the push-in adapters.

11.(B) Locate the factory fill neck on the inboard side of the truck bed. If it is a 5/8” vent line, place it upon the 5/8” portion of the Vent-Line Adapter. If it is a 3/4" vent line, place it upon the 3/4" Vent-Line Adapter.  Mark the vent line where the cut should be made. Insure you will have enough hose to slide over the adapter. Cut a small section of either the 5/8” or 3/4” vent line. Place a large hose clamp on each side of the cut section. Insert the Vent-Line Adapter and tighten the hose clamps.  

12. Mount the inline pump near the Vent-Line Adapter, insuring the fuel flow is going from the auxiliary tank to the factory tank. Run the 3/8” supply hose & the 5/16” return hose to the Vent-Line Adapter Area. Attach the 3/8” supply hose to the inline pump. Place and tighten with a hose clamp. It will be necessary to cut the excess hose off. Attach the remaining portion of the 3/8” hose to the other side of the pump. Place and tighten with a hose clamp. Route the 3/8” hose to the Vent-Line Adapter and place upon the 3/8” port. Route the 5/16” hose to the Vent Line Adapter. Place and tighten with a hose clamp.

13. The WHITE wire that was run through the fire wall will connect to the WHITE wire on the pump. (NOTE: the wire may appear off-white). The BLACK wire will connect to the BLACK wire on the pump.

14. The BLUE wire will splice into the Factory Sending Unit Wire. To ensure proper reading, attach the blue wire as close to the top of the factory sending unit as possible. (Going from the inboard side of the factory tank, it is possible to feel the factory wiring harness. Pull the factory harness towards you to attach the BLUE wire to the factory sending unit wire).  (Purple-GM, Yellow with purple stripe-2008-current Ford, Yellow with white stripe 88 to 07 Ford front tank, Blue with black stripe 03 to 05 Dodge, Blue with white stripe-98-02 & 05-08 Dodge) (See owner’s manual due to variations of truck wiring).

15. The YELLOW wire will connect to the Yellow wire from the Auxiliary Tank. The GREEN wire from the auxiliary tank needs to be connected to Chassis Ground.
